Torsion Springs are helical springs that exert a torque or rotary force. Each end of a torsion spring is attached to other components, and when those components rotate around the center of the spring, the spring resists, trying to regain its original position. While the name suggests otherwise, torsion springs are subjected to bending stress rather than torsional stress. They can store and release angular energy or statically hold a mechanism in place by deflecting the legs about the body centerline axis. Torsion springs are typically wound close but are able to have pitch to reduce friction between the coils and offer resistance to rotationally applied force (twist). torsion springs can be designed to work in a clockwise or counter-clockwise rotation, thus determining the direction of the wind, depending on the application.
Torsion Spring Characteristics
• Helical coiled spring that exerts a rotating force or torque.
• The shape of torsion springs is very versatile but in essence it is comprised of a body of coils and two legs.
• Torsion springs are typically made from round wire although square and braided wire is not uncommon.
Basic Torsion Spring Design Requirements:
- Material
- Wire size [d]
- Coil Diameter: Inner [I.D.] Outer [O.D.] or Mean [D]
- Total Coils [Nt]
- Leg Lengths
- Loads at corresponding deflection [P1, P2, H1, H2]
